HIGH-PRESSURE NEUTRON-DIFFRACTION - PRESENT AND FUTURE POSSIBILITIES USING THE PARIS-EDINBURGH CELL

The Paris-Edinburgh cells have been used over the past few years to ob tain fully refinable neutron diffraction patterns by time-of-flight me asurements on large volume powder samples up to 10 GPa at ambient temp erature. The use of this type of instrument can be extended to i) high er pressures, well. above 20 GPa, ii) experiments at low and high temp erature iii) the study of samples which are liquids or gases at ambien t, and iv) to the study of single crystals in the angular dispersive m ode.
